This is much the same as my Chicken Curry but first the balls need to be prepared. Finely dice medium onion and in a bowl mix that into 500G of mince along with curry powder (Mackenzies Clive of India) and a beef cube. Now the fun part; compress and form into balls, put aside and start prepping/cooking the main curry sauce. PM for recipe.
